25.00298.15 K94.650.9801Acetonitrile-rich phase
 Method/Apparatus/Procedure:
   The analytical method was used. Each two-phase mixture was stirred intensely in a 70 mL equilibrium cell for 2 h and then was allowed to settle for 2 h at 25.00 °C in a thermostated water bath. Two liquid samples in equilibrium were withdrawn with Hamilton syringes and were analyzed by means of a gas chromatograph and an electronic integrator.
